|Jules asked if I would write a tip on how to construct a convertible collar with yoke by sandwiching the collar between the yokes. I've always done it this way so I'm often surprised when patterns have you leave an opening in the back neck instead. IMO, the sandwich method is soooo much easier! Please click on the link above for step-by-step directions with photos.
If anything is unclear or if I can improve on anything, please let me know. :-)
